@kyra probably not much to the average consumer but it'll be easier to smooth out demand if these get cheaper and easier to run, the fact that they're extremely fast to charge and discharge is great. I doubt they'll work in something like a car because of the large magnetic fields involved https://en.m.wikipedia.org/wiki/Superconducting_magnetic_energy_storage
@kyra energy density is also an order of magnitude lower than traditional batteries, though idk if that changes once you don't need to supercool them
